Abstract: A wheel spring support frame for attaching a leaf spring to the underside of the frame of a vehicle. The support frame has a substantially U-shaped cross-section with parallel sidewalls connected by an upper member attached to the vehicle's frame. The sidewalls have spaced, downwardly projecting flanges which oppose the flanges of the other sidewall. Reinforcing spacers extend between the sidewalls, adjacent to the flanges. Each flange has an aperture aligned with the aperture of the opposing flange for accepting a fastener. The ends of the leaf spring are supported by the fasteners.
